Spoilers are an additional illustration of auto parts that have originated on the race track. Made to help "spoil" the unfavorable air movement across the back end of the motor vehicle on race cars, the spoiler’s job was to keep the car down on the track. Further, they added stability, cornering, and aerodynamics to the race cars, creating a complete new dimension in the wacky world of auto racing.

The Rear Wing, on the other hand, is designed to generate a "down-force" at the back end of the vehicle, helping it to stay low to the ground. It is very effective for high speed cornering and general stability on the road, keeping the car "grounded". It is called a Wing because of its resemblance to an aircraft wing, although mounted in reverse.

The Universal Spoilers are just what the name sounds like - one particular dimension piece fits all. They may be made in a very specific design or shape, but without make and model differences. You’ll need to perform some careful measuring with these to insure they fit properly across the back of your particular automobile.
